I am looking for a function that will replace last occurence of a substring from a string: tmpStr: xxx, yyy, zzz, sss, The desired outcome: xxx, yyy, zzz and sss (ie: remove last letter and then replace last occurrence of ",") The string can differ,
* xxx,
* xxx, yyy,
* xxx, yyy, zzz,
Do anyone of you have a neat fuction for that? I will be so happy for all input!
Is it possible to convert "xyz123456xyz789" into "123456xyz789"? What I'm trying to say is, remove the first occurence of "xyz" from the string, so that all the other occurrences of "xyz" that aren't the first one, remain.

I need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.
function selected_item() {
if (Selection=="Select State")
alert("Select the State");[code]....
I tried this:
var state=Selection.substring(0,11); and then string would be equated to state variable. But it is not working.
Here is my code:
<script type="text/javascript">
var str="Welcome to Microsoft! Microsoft Microsoft";
var stringToBeFound = 'Microsoft'
var ReplaceString = 'site'
document.write(str.replace(stringToBeFound , ReplaceString ));
</script>
My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database
I ran into a problem that I could not fix myself, I am trying to replace a string with another string, the replace lines look like this:
Code:
var word = document.getElementById("word").innerHTML; document.getElementById("word").innerHTML = wordd.replace(/B/g, '<span class="style106">B</span><span class="style107"> </span>'); It works just perfectly if left alone, but I need to replace every letter inside this string, adding those style and span tags around each and every letter. So if I add another line to this code, like this:

I was tring to write a function to make that took the letters that a
user is searching for and making the first occurrence of it bold in
the results (ignoring the case).
>From reading javascript books and looking at posts in this group, I
thought this would work. Perhaps I misunderstood what $1 is. But in
the results, I am getting a bold $1 with IE6.
How can I determine what the occurrence of the phrase is in the
correct case?
I realize I can write this parsing the string without regular
expressions but I thought this would be cleaner.
var match = new RegExp( escapeCharsForRegExp(typedLetters), "i");
if (match.test(text))
{
text = text.replace(match, '<b>' + '$1' + '</b>' );
}
Three questions
1)
I have a string function that works perfectly but according to W3C.org
web site is syntactically flawed because it contains the characters </
in sequence. So how am I supposed to write this function?
String.replace(/</g,'<');
2)
While I'm on the subject, anyone know why they implemented replace using
a slash delimiter instead of quotes? I know it's how it's done in Perl
but why is it done that way?
3)
One last regexp question:
is it possible to do something like this:
String.replace(/<(.*?)>(.*?)</$1>/ig,'<$1>$2</$1>');
This is just an example where a sub-match used in a regular expression
must sub-match again exactly as it did the first time later in the same
string. But I don't know how to do that in a regexp although it seems
like it should be possible.

I've a function like this: Code:
function submit_msg() {
if (egsd.value == 'yes') {
write_msg("<b>" + chatkeo.value + " : " + chatmsg.value + "</b><br />");
} else {
write_msg(chatkeo.value + " : " + chatmsg.value + "<br />");
}
chatmsg.value="";
}
Now I need to do some string replace in chatmsg.value, ie, I need to look for some piece of text in chatmsg.value, and in case they are present (there may be multiple occurences of the same), to replace them with something else. This is what I got by doing a google search: Code:
function replaceAll( str, from, to ) {
var idx = str.indexOf( from );
while ( idx > -1 ) {
str = str.replace( from, to );
idx = str.indexOf( from );
}
return str;}
chatmsg.value = replaceAll( chatmsg.value, "string to replace", "new string" );
And I place this second function just above the previous one. But it's not working. Any help friends?

I have a JavaScript string. I want to replace all consecutive
occurrences of whitespace characters like spaces, tabs, newlines, and
form feeds with another string.
For example, say I have a string consisting of:
-- 3 spaces
-- The characters "hello"
-- 2 newline (
) characters
-- The characters "goodbye"
-- 5 spaces
After applying some sort of regular expression to replace consecutive
occurrences of whitespace chars with the string "X", the string should
consist of the following:
-- The character "X"
-- The characters "hello"
-- The character "X"
-- The characters "goodbye"
-- The character "X"
How could I do this using regular expressions? I'm quite familiar with
JavaScript but don't know anything about regular expressions or using
them in JavaScript, so please show me step-by-step how it's done.
I have the following plugin to "deobfuscate" an email:[code] At the moment I have two problems:
1.I want to being able to use other values than AT and DOT. So instead of having:email = email.replace(/ at /gi, "@").replace(/ dot /gi, ".");I would like to have something like:email = email.replace(/ options.At /gi, "@").replace(/ options.Dot /gi, ".");But this is not working. How can I make it work?
2.What the plugin does is replace:<span class="Email">name at domain dot com</a>[code]
i have phone number on the page. Let's say 0208 123 45678 and i want to replace it with 0207 123 9999. Thing is, phone number is not in one type of tag, id or class.All i can tell you, it is somewhere throughout the body tag.
View 1 Replies View RelatedI am running a search on my web site which uses jQuery to take the search terms and build up a URL based on them. For example, if someone searches for "chair" my URL will be appended with /chair/. However, if someone searches for something which is two words, for example "chair covers" I need the space in between to be replaced by a "+" sign so the URL will now be appended with /chair+covers/ I'm not sure if it is possible to string replace in jQuery?
Here is my current code:
function sendSearchInput(whichelement,hiddeninput,formid) {
hval = $("#"+hiddeninput).val();
$("#"+formid).submit(function() {
if ($("input:#"+whichelement).val() != hval) {
var searchval = $("#"+whichelement).val().toLowerCase();
$("#"+formid).attr("action","retail/search/"+searchval+"/");
return true;
}
$("input:#"+whichelement).focus();
return false;
});}
This will basically check that the form is not the default value (specified in the hidden field "hval") and then change the search term to lowercase and append the URK using "attr". I have tried a couple of methods including
var test = searchval.text().replace(' ','+');
And then trying to alert "test" to check it but the function just simply doesn't work.
I'm new to Jquery, and i was wondering how i could rename a string like "hat" to "het" by replacing "a" with "e"in my labels..
